My 10 cents (we no longer have 1 cent or 2 cent coins anymore, not even 5 cent ones):

0.01 :  It appears that Cygwin will move to Dwarf2 EH
0.02 :  MinGW64 only supports DW2 EH
0.03 :  MS compiler only supports table-based EH on Win64
0.04 : Code written in other languages besides C++ (namely Java and Ada) benefit
enormously from the use of DW2 EH.
0.05 : If you believe DW2 EH will break your windows app, you have opportunity with GCC
4.3.0 20080502 (alpha) to demonstrate (or not) your fears.  Testcases are good.
